Abstract

In general, this disclosure describes techniques of determining a backset for client devices attempting to download data of a live transmission. A backset is an amount of temporal delay that the client devices are delayed by when viewing the live transmission. As described herein, a media content provider may determine a recommended backset for each client devices based characteristics of the client device. Each client device may then be backset by the determined value, or may calculate its own backset based on the recommended backset. Establishing a backset for each client device may avoid rebuffering of live transmission data.
